A big lie is a gross distortion or misrepresentation of the truth primarily used as a political propaganda technique. The German expression was first used by Adolf Hitler in his book Mein Kampf (1925) to describe how people could be induced to believe so colossal a lie because they would not believe that someone "could have the impudence to distort the truth so infamously". Hitler claimed that the technique had been used by Jews to blame Germany's loss in World War I on German general Erich Ludendorff, who was a prominent nationalist political leader in the Weimar Republic.

Accusation in a mirror (AiM) is a technique often used in the context of hate speech incitement, where one falsely attributes one's own motives and/or intentions to one's adversaries. It has been cited, along with dehumanization, as one of the indirect or cloaked forms of incitement to genocide, which has contributed to the commission of genocide, for example in the Holocaust or the Rwandan genocide. By invoking collective self-defense, accusation in a mirror is used to justify genocide, similar to self-defense as a defense for individual homicide.
The strategy was used by Joseph Goebbels.
